“…Behavioral responses based on speed of movement can also be interpreted differently, with opposing ecological consequences: a reduction in movement can be caused either by a lethargic response due to a toxicant or by reduced stress (Díaz‐Gil et al ). In addition, it was observed that hypoactivity occurred in the fish Oryzias latipes after exposure to lethal concentrations during the short term, but that after exposure to sublethal concentrations in the long term, the fish responded with hyperactivity (Khalil et al ).…”

“…The first methods simulated a gradient to assess the avoidance and preference responses of organisms by injecting clean water and a contaminant in the opposite extremities of a tube (see details in the reviews by Cherry and Cairns and Jutfelt et al ). A number of studies exist that used a nonforced exposure approach intended to simulate 2 (toxic and nontoxic) aquatic environments and a mixed zone between them (Folmar ; Gunn and Noakes ; Nakamura ; Hartwell et al ; Gray ; Little et al ; Smith and Bailey ; Saglio et al ; Ren et al ; Díaz‐Gil et al ).…”

The idea that the hazard of contaminants is exclusively related to their toxic effects does not consider the fact that some organisms can avoid contamination, preventing toxicity. Although inferences about avoidance are made in most behavioral ecotoxicology studies, assessment of the real spatial displacement (organisms moving toward another habitat to escape contamination) is difficult due to the type of exposure (confined and mandatory) used in the bioassays: a forced exposure approach. A complementary approach using nonforced exposure systems to assess how contaminants affect the spatial distribution of organisms in a bicompartmented (toxic or nontoxic) environment has long been described. Recently, this nonforced approach has been developed to include a multi compartmented system in which different samples can be simultaneously tested. The aim of the present review was to describe the importance of the nonforced, multicompartmented exposure approach to simulate a gradient or patches of contamination, to describe the 2 main exposure systems, and to highlight the ecological relevance of including spatial avoidance and habitat preference in ecotoxicological studies. The multicompartmentalization of the system makes it possible to simulate more complex scenarios and therefore include new ecological concepts in bioassays. We also contrasted spatial avoidance in the nonforced exposure systems with the behavioral endpoints measured under other exposure systems. Finally, we showed that the nonforced, multicompartmented exposure approach makes it possible 1) to improve environmental risk assessments by adding the dispersion pattern of organisms in a multihabitat scenario, and 2) to integrate ecological concepts such as recolonization of recovering habitats, loss of habitat connectivity, habitat fragmentation, and contamination-driven metapopulation, which have received limited attention in ecotoxicological studies.

“…The sampling site in Leucate, which is located near the entrance of the large "Étang de Leucate" lagoon, was the only one where those species were regularly collected (44 glass eels and 15 S. aurata larvae; Table S2 in the Supplement). Both species suffer intense fishing pressure due to their high commercial value and are the focus of numerous studies (e.g., Koumoundouros et al 2009, Faria et al 2011, Díaz-Gil et al 2017, Naisbett-Jones et al 2017, Cresci et al 2017. The site in Leucate therefore appears as a good candidate to study the early life stages of these species in the region.…”

Most coastal fish species spend their early life stages in the pelagic environment, before settling in coastal habitats. The variability in the arrival of larvae to coastal habitats provides information on the species’ biology and recruitment potential. To explore the dynamics of larval fish supply to coastal habitats in the NW Mediterranean Sea, 13 sites were monitored using light-traps, from July 2012 to December 2015. Most variation in catches per unit effort (CPUE) among topographic basins and species were statistically significant for high (quantile 75%) and very high (quantile 90%) catches only. At the yearly scale, CPUE displayed strong seasonality, and 3 main species assemblages were detected in late spring-early summer, summer and late autumn-early winter. At the monthly scale, CPUE were higher around the new moon for all quantiles and temporally autocorrelated at a lag of ~28 d. Larval supply also varied spatially with site-specific associations and with riverine influence. Altogether, these results confirm that the previously described patterns of larval supply observed in tropical and subtropical environments (e.g. the high variability at all spatial and temporal scales and the strong influence of the moon) also apply to Mediterranean fish assemblages. Our quantile-based approach demonstrated that the larval supply in the NW Mediterranean Sea is a solid candidate for monitoring the state of the marine ecosystems, highlighting the need to continue such time series.

“…In a series of flume experiments, Vicente et al (2020, this TS), showed that non-naïve larval sand-smelt Atherina presbyter actively selected water from locations with which they were familiar or where conspecifics had been dwelling, adding to the few studies demonstrating important effects of chemical cues (presumably for orientation in the wild) on early stages of temperate species (e.g. Díaz-Gil et al 2017, Fobert & Swearer 2017. Another fundamental trait of larval behavior that drives survival and geographical persistence of populations is swimming ability.…”

The first weeks in life are crucial for the fate of fish. During this period, fish show large dispersal rates and suffer from massive mortality due mainly to predation. Intrinsic and extrinsic processes (growth rates, advection, behavior, diseases) affect this mortality and have profound consequences on populations. For a century now, describing the distribution, physiology and dynamics of fish early life phases has been the focus of intense research, building a solid community of scientists that met at the 43rd Annual Larval Fish Conference, held in Palma, Spain, 21-24 May 2019. The present Theme Section consists of 19 papers that are a sample of the research presented at the conference. The papers are organized around 5 main topics: (1) mortality estimation and process understanding, (2) parental effects on larval fish ecology, (3) larval settlement to juvenile grounds, (4) early life stages of fish within food webs, and (5) contribution of early life stages of fish to assessment and management. Contributions to this Theme Section focus on hot topics as well as old paradigms; the latter continue to elicit much research work, which has benefited from recent advances in technology.
